Specification of Letters Patent.

Application led October 24, 1910. Serial No. 588,722.

To-all lwhom it may concern vide novel means whereby both the front and.

rear axles of a self-propelled vehicle, may

be simultaneously driven; to provide driving mechanism ina self-propelled vehicle, the component elements of which mechanism are assembled in a novel and improved manner; and, generally, to improve the driving mechanism of a motorpropelled vehicle.

With the foregoing and other objects in i view which will 'appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that chances in the precise embodiment of invention tlierein disclosedcan be made within thesoope of what'is claimed without departing from the spirit 'of the invention.'

In'the drawings, Figure 1 is a fragmental side elevation showing one form of the invention, parts being broken away; Fig. 2 is a vertical section of the mechanism whereby the axle sections are connected with the drive wheels; Fig. 3 is a vertical section on the linev being understood that such a vehicle is but one of the many forms of structures with which the device may be assembled.

Certain portions of the frame of the vehi-v cle are shown, 'for instance, a transverse upper beam 1,'a transverse lower beam 2, and a longitudinal beam 3, the hood 1n which the engine is housed, being denoted by the numeral 4. The front wheels are denoted by the numeral, the rear wheels by the numeral 6, and the casing by the numeral 7, in which casing the rear axle 8 is rotatable to drive the rear wheels 6. A longitudinally extending drive shaft 91 is shown, and suitable mechanism located within a casing 10 operatively connects the drive shaft 9 with I the rear axle 8. B means of a universal joint 11, the forwar end of the drive shaft 9 may be connected with an auxiliary shaft 12, mounted for rotation in a bracket 14, supported upon the longitudinal beams 3 of the frame, or in any other suitable manner. The forward end of the auxiliary shaft 12 extends tinto a casing 15, containing suitable mechanism whereby the auxiliary 'shaft 12 may be connected operatively with. a transverse counter shaftI 1G. This counter shaft l 1G is su ported in a manner to be described herelna ter.

Secured vto the transverse lower beam 2 of the Jramere spaced boxes 17. A sleeve 1S is rotatable in each of vthese boxes 17, and within the sleeve 1S is located a collar 19 secured to the sleeve 18 for rotation therewith- The sleeve 18 and the collar 19 constitute a bearing structure, rotatably mounted in the boxing 17.

Pinions 20, constituting drive wheels, are shown, these pinions 20 being mounted upon the forward axles 21, which axles 21 carry the front wheels 5. The axle sections 21 are provided intermediate their ends with substantially .spherical heads 22. 2O and the collars 19 are disposed upon opposite sides of the-heads 22, the pinions 20 and the collars 19 being provided upon their adjacent faces, with rounded bearing surlaces 23, adapted to bear against the head 22.

`r1`he collar 19 is secured to the pinion 20 The pinions' iol spd

to rotate therewith, the collar 19 being, as hereinbefore pointed out, secured to the sleeve 18 to rotate therewith. The head 22 isA provided with an outstanding lug 24, adapted to register in mating recesses 25 in 'the'adjacent end faces of the collar 19 and the pinion 20. This lug 24 and the recesses 25 constitute interengaging elements, whereby the collar 19:, the head 22 and the pinion 20 may beconnected for simultaneous rotation. The remote faces of the collar 19 and the'pinion 20 are provided with inwardlyLex- `tended conical recesses 26 in which the forward axle section 21 is mounted.` These recesses 26 permitl the axle section 21 to swing in a horizontal plane with the lug 24. as a center.

To the inner face of each boxin 17 a plate 27 is secured, andto the outer ace of this plate 27, horizontal guide bars 28 are at-y tached. A closure plate 29 slides between the guide bars 28, the edges of the guide barsV 28 ybeing undercut as shown at 30, so as to hold the closure plate 29 in place.-

n the plate 27 there` is an elongated slot 31, seen most clearly in Fig. 3. In this slot 31, the axle section 21 is free to swing in a horizontal plane. there is an opening 32, adapted to receive the axle section 21. This opening 32 in the plate 29 is,v however, of substantially the same cross section asfthe axle section 21, 'so

that as the axle section slides in the slot 31 of the plate 27, the closure plate 29 will move to and fro with the axle section. Brackets 33 are secured to the boxings 17, and it is in these brackets 33 that the counter shaft 16 is journaled for rotation.

Secured to the counter shaft 16 are spaced pinions 34, one of which is clearly seen in 4 Fig. 1. Each of these pinions 34 meshes into journaledyforrotation inthe boxings 17.

one of the pinions 20.

At this point it may profitably be stated that when the drive shaft 9 is rotated to actuate the rear axle 8, the 'auxiliary shaft 12`v will be put'into rotation at the same time, causing the counter shaft 16 to rotate,

"thepinions 34 rotating the pinions 20,. these pinions 20 engaging the lugs 24 and causing the forward axle sections 21 to' rotate, thus putting the front -wheels 5 into motion, un-

er vthe impulse of the primeinover, and simultaneously with the rear-wheels 6. The lugs 24, engaging the collars 19 will cause Athese collars, together with their attached sleeves 18, to"rotate, the sleeves 18 being Ilowever,'while the forward wheels 5 are thusbeing' rotated, it willbe seen that the .axle sections 21 may swinvin a horizontal lplane, under the impulsey ofz'suitable steering l mechanism, thus permitting the vehicle to round a corner, the axle sections 21 .sliding in the slots 3l in the plates 27, andcaraying In the closure plate 29 the boxing, and to which the with them, in their sliding movement, the closure plates 29, the pinions 20 and the'collars 19 serving as bearings upon which the heads 22 of the axle sections 21 swing, as the axle sections are mpved to and fro in a horizontal plane, under the impulse of the steering mechanism.

From the foregoing it will be seen that both the forward and rearward axles of a motor propelled vehicle may be driven simultaneously from a common source of power, the steering oi the vehicle being readily efected without interfering in any way with the positive drive of the forward axle of the vehicle.

Having thus described the invention, what is claimed is 1. In vehicle driving mechanism, a rigid axle section 'adapted to receive a traction wheel and rovided with a bearing head; a drive wheelpupon the axle section and bearing against one side of the head; a collar upon the axle sectin and bearing against the other side of the head; interengaging elements upon the head, the collar and the drive wheel to secure aysimultaneous rota'- tion thereof, but permitting the axle section to swing in the collar anddrive wheel; a sleeve secured to the collar; a bearing in which the sleeve rotates, and a closure for the bearing slidable with the axle as the latter swings.

2. In vehicle driving mechanism, a frame;

swing in the pinion; a member rotatable in inion is secured; a counter shaft rotatab y supported section, the axle section being mounted to upon the boxing; and a pinion upon the g countersha-ft, meshing into the first specified pinion.

3. In vehicle driving mechanism, a frame; a boxing mounted upon the frame; a drive whe a sleeve projecting from one side of the drive wheel and journaled for rotation in the boxing; a collar located within the sleeve and detachably secured to the sleeve; and a rigid axle section, adapted to receive a. traction wheel, the axle' section being provided with a bearing head mounted between the drive whe'el and the collar, for Swingin movement, the bearing head being connecte with the drive wheel to secure a rotation of the traction wheel.

4. In vehicle driving mechanism, a frame; a boxing mounted upon the frame; a bean ing structure journaled for rotation in the being mounted to swing in the drive wheel In testimony that we claim the foregoing 1o and n the bearing Structure, and being opas our own, We have hereto aixed our sigeratively connected with the drive wheel to natures in the presence of two witnesses.

secure a rotation thereof' a plate applied to the boxing and provided with 'an opening GEORGE P HENDERSON' .in Which the axle section is adapted to move; JOHN F' PARROTT' guides upon the plate; and a closure/for the Witnesses:`

opening, mounted to move in the guides, and J. FRANK WATSON, aotuable by the axle section. S. C. CATCHING.
